ALlMENTARY-PASTE-DRYING APPARATUS.

SPECIFICATION forming partof Letters Patent N 0. 735,931, dated August11, 1903.

Application filed November '7, 1900. Serial No. 35,765. (No model.)

Hertofore the drying of such alimentary paste,

could be efficiently effected only by the atmosphere or in large dryingapparatus in which the temperature is slightly raised.

These methods require much time and space, I

while other quick-drying processes are objectionable in that the pasteis frequently cracked by reason of the quick drying of the surfacethereof.

The object of the invention is therefore to avoid the objections of theair-drying and of the artificial-drying processes.

The invention consists in the construction, novel combination, andarrangement of parts fully described and claimed hereinafter.

In the accompanying drawings, Figure 1 is a vertical sectional view of adrying apparatus constructed in accordance with my invention. Fig.2 is adetail view of a pastereceiving shelf or drawer.

Referring to the drawings, a represents a casing made of suitable form,dimensions, and material.

1 designates a suitable ventilator, such as a turbine-ventilator,arranged within the upper part of the casing a, and the shaft of whichis j ournaled in bearings 17 18, secured to the casing a, saidventilator being actuated by means of friction-pulleys 19 or otherwiseand a suitable motor. Arranged within the compartment or casing at theupper part of the casing a is a heater 13, preferably formed of wingedtubes, adapted to receive hot steam, 850., a diagrammatical view ofwhich is shown in Fig. 1. Under said compartment or casing are arrangedthe removable shelves 2 for the reception of paste to be dried, avertical passage 3 4 being provided on each side of said removableshelves. The front wall 20 of the eration and through which the shelvesare introduced and removed. The ventilator 1 being actuated, air issucked through 'the passage 3 and into the upper compartment or casing,where said air is heated by the tubular heater 13 and then forced downthrough the passage 4 into the spaces between the paste and through thehollow spaces in said paste, (macaroni,) whereby the latter is readilyand perfectly dried.

The apparatus thus constructed may be employed for drying paste in bulkinstead of arranging said paste in separate layers,whereby considerablesaving of time is obtained, as the pastes-for instance, macaroni-may betaken from the compressing-machine and directly introduced into thedrying appara tus, wherein the current of air is produced parallel withthe tubes of 'paste and forced partially through the tubes of paste andpar tially through the intermediate spaces between said tubes. For thispurpose I have constructed special shelves or drawers 2, formed of aflat plate 21, Fig. 2, having two upwardly-projecting flanges 22 22,between which the tubes of paste are received as they come from thecompressing-machine.

Having fully described my invention, what I claim, and desire to secureby Letters Pat out, is-

1. In an alimentary-paste-drying apparatus, the combination of a lowercasing having one side movable and adjustable, a pastematerial-receivingspace located centrally of said casing; an upper casing having a bottomand provided with a central opening in one side and an air-inlet openingin the opposite side, said inlet and opening communicating with theinterior of the lower casing on opposite sides thereof; a heater in saidupper casing; and a rotating ventilator adjacent to said central openingon a plane above said paste-material-receiving space, said ventilatorproducing continuous air-currents on opposite sides of said shelveswithin the lower casing through said paste-inaterial-receiving space inone direction and through the upper casing.

2. In an alimentary-paste-drying apparatus, the combination of a lowercasing; a vertically-slidin g plate closing one side thereof; an uppercasing provided with a central opening in one side and an air-inletopening in the opposite side, said inlet and central openingscommunicating with opposite sides of the interior of the lower casing; aheater in said upper casing; removable shelves for the paste materiallocated centrally of the lower casing, and a rotating ventilatoradjacent to said central opening, said ventilator producing continuousair-currents on opposite sides of the removable shelves Within the lowercasing, through the shelvesin one direction and through the uppercasing.

3. An alimentary-paste-drying apparatus comprising a lower casing; avertically-movable plate closing one side of the lower casing; an uppercasing provided with an airinlet opening in one side and anair-discharge opening in the opposite side; a heater within the uppercasing; a plurality of superposed paste-shelves located centrally of thecasing, the air-inlet and air-discharge openings of the upper casingbeing located at points outside JOSEPH ALLOATTI.
